1. 9.1 TRANSFORMAIONS

2. Objective: To Identify Rigid Motions
To Find and Provide Transformations of Figures

3. Vocabulary: Transformations Preimage Image Isometry
Composition of Transformations

4. Solve It:

5. TYPES OF TRANSFORMATIONS
Reflections – The flip of a figure over a line to produce a mirror image.
Rotation – A geometric turn of a figure around a fixed point.
Translation – The slide of a figure from one position to another.
Dilation – A transformation that alters the size of a figure, but not its shape.

6. Preimage to Image B’ A’ C’ B
Its matching point on the corresponding figure is called its image. D’ A C D
Each point on the original figure is called the Preimage

7. Rigid Motion:
A transformation that preserve the both distance and angle measures.

8. Rigid Motion:

9. Rigid Motion Solution:
The above transformation is NOT a rigid motion since the distance of the sides is not the same
